* Add MPI::Status methods Set_elements() and Set_cancelled()
* Added a bunch of comments in various places in the MPI C++ bindings
implementatio just to explain what's going on (because C++ can hide
a lot from you)
* Insert C++ callbacks for the MPI_Grequest callback functions
registered by MPI::Grequest::Start(). These callbacks keep a
little meta-data (created by Grequest::Start()) that allow the
proper callback signatures from C (i.e., from ompi_grequest_<foo>()
in libmpi.a -- C code), translate arguments as required, and then
invoke the callbacks with proper C++ signatures (i.e., call
user-defined callbacks with C++ function signatures).

1. Added reporting points around the xcasts in MPI_Init. Note that these times will include time spent waiting for a trigger to fire, which is why the times between stage gates did NOT include these times initially. The inter-stage-gate times still do NOT include the xcast time - the xcast time is reported separately.
2. Added the process vpid on the MPI_Init timing reports for clarity.
3. Added a report from the xcast function on the HNP that outputs the number of bytes in the message being sent to the processes.

size of the complex type as determined by configure; not the size of
the next larger complex type (i.e., a complex*N is 2 real*(N/2)'s, not
2 real*N's).

Without this a compiler could assume that the counter is not updated
my the malloc call and remove the test in the assert and always trigger
the assertion.

__DARWIN_UNIX03 is defined on Tiger when compiling PPC 64 code, so
we can't use that.

Ticket 575 --> https://svn.open-mpi.org/trac/ompi/ticket/575
* Add some more error checking to GREQUEST_START
* Move the error checking in GREQUEST_COMPLETE up to inside the
MPI_PARAM_CHECK block, where it belongs
* Invoke the gen request query_fn in all the Right spots (per MPI-2:8.2)
* Distinguish between grequests created from C and Fortran
* Use the OBJ system to reference count to release the grequest at
the Right time and invoke the grequest free_fn properly (see
lengthy comment in grequest.c above the destructor)
* Have ompi_grequest_complete() call ompi_request_complete() rather
than [poorly] copy the contents of ompi_request_complete()
* Fix Fortran function callback pointer typedefs to use proper
Fortran types
* Edit ompi_request_test* and ompi_request_wait* to properly handle
generalized requests. This adds an "if" statement in the critical
path for all the back-end test* and wait* functions :-(,
but fortunately George took out two "if" statements from the
critical path last week. So we're still ahead. :-)
* Move ompi_request_test() out of request.h and into request.c (all
other test* and wait* functions were already in the .c file -- and
ompi_request_test() was too long to be statically inlined anyway)

Had group discussion about this on the weekly call. The decision was
that we should pass the real error code to the back-end exception
handler because it's pretty useless to pass MPI_ERR_IN_STATUS to the
back-end exception handler (because exception handlers don't have
access to the request or the status - this has potential issues for
fault tolerance kinds of scenarios). So in TESTALL, TESTSOME,
WAITALL, and WAITSOME, we examine the error code and if it's not
MPI_SUCCESS, return MPI_ERR_IN_STATUS.

mca_btl_openib_endpoint_connect_eager_rdma() is called recursively. He also
noticed that orte_pointer_array_add() can't fail because we allocate max number
of elements at init time. So just remove error handling and locking. No locking
- no deadlocks.

something is going wrong down in the code it is removed from the array. So add
mutex to prevent concurrent access to the array from different threads.

1. ORTE_RMAPS_DISPLAY_AT_LAUNCH: pretty-prints out the process map right before we launch so you can see where everyone is going. This is settable via the command line option "--display-map-at-launch"
2. ORTE_RMGR_STOP_AFTER_SETUP: just setup the job and then return from the spawn command.
3. ORTE_RMGR_STOP_AFTER_ALLOC: return from the rmgr.spawn call after allocating the job
4. ORTE_RMGR_STOP_AFTER_MAP: return from the rmgr.spawn call after mapping the job. This gives folks a chance to retrieve and graphically display the map, let the user edit it, and store the results. They can then call "launch" on their own and the system will use the revised map.
Enjoy! My personal favorite is the first one - helps with debugging.

Setup subscriptions to correctly return the MPI_APPNUM attribute.
Fix an unreported bug that was found. The universe size was incorrectly defined in the attributes code. As coded, it looked for size_t values and based its size computation on those numbers. Unfortunately, the node_slots value had been changed to an orte_std_cntr_t awhile back! So the universe size was never updated.
Update the hello_nodename test to check for MPI_APPNUM.
Add a definition to ns_types for ORTE_PROC_MY_NAME - just a shortcut for orte_process_info.my_name. Brought over from ORTE 2.0 as it will be used extensively there.
